Continents and Oceans

Young Entrepreneur · 01-20-04, 12:47 PM

My question is: Are all land (couldn't find a better word

)floating on the ocean?

Japan and Hawaii is a piece of land that is floating on top of the ocean, right?
Then is the United States, Canada, Europe, and all large land floating on top of the ocean or does the land reach all the way to the bottom of the ocean surface?

I probably lost some of you. If you understand what I am saying, please post whatever knowledge you have or if you're confused, ask me questions.

I don't know the answer to your question but I know that Antartica's surface is only a small percentage of its body. Meaning, large percentage of Antartica is below the sea level is much immeasurable than we think. Sorry for not answering your question.

What class is this question for?

Tough question. All countries should be floating if the Supercontinent was a fact.

I would think the continents are all floating because remember, Earth is composed of four layers (Upper Mantle, Lower mantle, Inner core and lower core). Not sure how deep the ground level is though. And the ocean is above the upper mantle layer.

Hmm... Seeing as how I used to live on Hawaii. I think It might actually be touching the bottom of the ocean. Otherwise the Atlas would have to updated more often. Also I don't remember getting sucked under the island while scuba diving. But if your talking about a layered surface of the earth, lets just say I'm not a geology major.

It isn't for a class I am taking. Just something that popped into my head when I saw a National Geographics magazine.
Both of the answers make sense.
